Subject: [R] Automatic routine - help
Hi,
I would like to write a little automatic routine in R, but i am a too
much of a beginner for that. I will appreciate any help
regarding this
particular problem.
Let's suppose I have a data.frame with j columns (from 1 to n) and i
rows (from 1 to p). I would like to write a procedure which reads
every column j (j from 1 to n) and compare each value with the
interval [0,1]. If z(i,j) is less than 0, then replace z(i,j)
with 0. If z(i,j)
is greater than 1, then replace z(i,j) with 1. If z(i,j) is
inside the
interval [0,1] then don't change. In the end I would like to have a
new data.frame with the new values.
I am not sure how complicated or long such a procedure might be,
so I will be very grateful for any help.
Thank you in advance,
Monica
